Free software for distance learning

Could any one tell about existence of FS projects for organizing automated online courses?

I have found only pages on GNU site and KDE. But there is nothing comparable to LearningSpace or WebCT

Also what do you thinks about creation of courses to educate aprentices of FS?
Main form of delivering knowlage to FS community now are tutorials and Howtos, but no questionaries, self-tests etc.
How do you thinks - is it worth of creating? Whould it help to improve quality of FS projects?

Have you heard of existing tools for tests delivering, checks, statistics mesurment (so teacher could enhance his questions or
improove tutorial of parts, which are made people to fail more oftern)?

You might want to look into MIT and Stanford's Open Knowledge
Initiative. It is a project that intends to create a full suite of
computer tools to aid in pedagogy. It is a very worthwhile endeavor,
and one that I hope some free software enthusiasts get involved in.
They are trying to make everything as standards-based as possible, and
everything is under a free license.
